DABBING MECHANISM USED IN WOOL-COIVIBlNG OR THE LIKE.

To all whom, it DMLZ/ concern:

Be it known that we, EDGAR GREENWOOD and JOSEPH GREENWOO subjects of the King of Great Britain and Ireland, whose postal address is 52 Cumberland road, Lidget Green, Bradford, in the county of York, England, have invented certain new and useful Improvements in and Relating to Dabbing Mechanism Used in WVool-Combing or the Like, of which the following is a specification.

This invention relates to improvements in dabbing mechanism used in wool-combing or the like, and has for its object the construction and arrangement of an adjustable automatic dabbing apparatus, which may be applied, by preference, to any Nobles wool-combing machine in such a manner that the use of-brushes which are liable to great wear and tear is obviated and that should hard or bulky substances pass to the combs either along with the wool or the like or accidentally such substances will cause the dabber to lift automatically and allow them to pass without injury to the combs or dabber.

In describing our invention in detail reference is made to the accompanying sheet of drawings, similar letters indicating similar parts, in which Figure 1 represents a side elevation of the mechanism employed. Fig. 2 represents a sectional plan on line a b of Fig. 1. Fig. 3 represents an end elevation, and Fig. 4 is a section on the line 4 4 of Fig. 1. Figs. 5, 6, 7, and 8 are detail views.

In carrying out our invention the pillar A, which is that portion of the framework of a Nobles comb which projects above and through the center of one of the small combcircles, is partially surrounded by bracket B, such bracket being substantially Y-shaped, as shown in Fig. 2. The base B of the said bracket is turned upward, as shown in Fig. 1. Such upturned portion engages with a similar upturned portion C of bracket D, which is provided with a slot C, Fig. 8. A set-screw or the like C passes through slot G into portion B for purposes of adjustment should such be required. The bracket D terminates in a bearing D.

Attached to the bracket B by means of setscrews B or the like is another bracket E,

Specification of Letters Patent.

Application filed September 13,1905. Serial No 278,353.

Patented which abuts against the pillar A and is partly circular in shape. Guide-faces E are formed at the sides thereof. The upper portion of bracket E carries the driving mechanism of the dabber, such mechanism consisting of driving-pulley F, which actuates a shaft F and crank F or other eccentric movement. The crank F is surrounded by the boss G of connecting-rod G, such connecting-rod terminating in a foot G provided with a slot H, with which engages the adjustable rod H. The rod H is of suitable length and is formed square toward its lower end, as shown at H A conical hole J is formed in one of the squared faces of the rod H for the purpose hereinafter described.

The rod H passes through an a erture K, formed in the dabber-carrier K. uch carrier is attached to or forms part of the Y- shaped lever L, the two arms of which terminate in bearings L. A shaft M passes through these bearings into bearing D, above referred to. The shaft M may be withdrawn when required.

The dabber itself consists of a suitable number of knives N and N, the knives N being for the smaller comb-circle and N for the larger one.

The knives N are mounted on small pins 0 and the distance apart of such knives regulated by sleeves 0 on the said pins. Such pins may form part of the arms 0 or consist of bolts passing through the same. The arms 0 pass upward into recesses or slots 0 in the dabber-carrier K and are held firmly in position by means of nuts or the like 0, which may be loosened when required, and the knives N moved toward or from the pillar A and retained in the adjusted position by means of adjusting nuts and screws, as O, or in any other convenient manner. Two knives are shown in the drawings; but it must be understood that any desired number may be used.

The knives N are arranged a suitable distance apart on rods P, and holes P are provided in knives N to allow the rods P to pass through same. The ends of rods P are retained in sockets Q, attached to the dabbercarrier K, and set-screws Q provided, whereby the said rods, and thereby knives N, may be adjusted and fixed.

The knives N may be arranged in such a manner that they may be adjusted as to distance apart without removal from the carrier.

The arms of lever L are provided with adjustable screws or the like R, which act on guide-faces E in order to prevent any longitudinal movement of the .dabber.

Immediately below the surface K in dabber-car'rier K is a hollow boss S, Fig. 4,

screwed internally for some little distance at S said boss S being integral with the carrier K. A pin T, terminating in a conical end T,

passes through boss S, such pin being provided with collars U and U U being fixed and U being loose, and a spiral spring U surrounds the said pin between such collars. An external threaded collar V engages the thread S at the end of boss S, such collar being provided with a cross-cut V, as shown.

with a cross -'pin T and a handle T A lock-nut V surrounds the projecting thread of collar V. The pin T is provided The conical .end T of the pin engages with the conical aperture J in rod H and may be brought out of contact by pulling the handle T and turning the pin T out of engagement with the cross-cut V.

An adj usting-screw V is provided opposite the pin T, such screw having a ball WV and ball-race V provided, as shown in Fig. 4, in order to retain the rod H in position.

Bolts X are provided in the illar A, and

i slots X are formed in the brac et E for the reception of the same. 35

.. rod H is also adjusted and the requisite num position.

ber of knives N and N placed in the required The bases of these knives at the top of the stroke project a slight distance below the top of the comb-pins. The conical end T of pin T engages w1th the conical hole I J. The pulley F is then driven in any convenient manner and the connecting-rod G operated, causing the rod H to move the dabber-carrier K up and down, such dabber carrier being centered by means of the Y- the conical hole J, and the knives will be raised, thus allowing the obstruction to pass under and clear of the knives. The carrier K will then resume its original position, the pin T returning automatically to aperture J. Should the knives require to be raised, the pin T may be drawn out, as before described, and the carrier raised. .A further stop or catch Z may be provided in the upper portion of carrier K whereby the said carrier may be held in the raised position.

It will be understood that for a Nobles comb two of the above-described apparatus will be reqiured.

What we claim as our invention is 1. A dabbing-machine comprising a carrier'K, a reciprocating rod G, a rod H adjustably connected to the rod G, said rod H having a conical hole therein, a pin T slidably mounted in the carrier K, a spring for normally holding said pin with its point in engagement with the conical hole and antifric-' tion means on the carrier K coacting with the rod H.

2. In combination with the bracket E, a second bracket D adjustably secured thereto, a shaft M carried by the bracket D, a carrier K connected to said shaft, knives adjustably mounted on said carrier, an adjustable rod H yieldingly connected to said carrier, means carried by the bracket E for reciprocating the rod H and a spring su ported on the bracket for assisting the trave of the carrier K.

In witness whereof we have hereunto set our hands in the presence of two witnesses.
